GeForce GTX 980 Ti vs Radeon RX 5700 XT

Intro

Compare all that to the Radeon RX 5700 XT, which comes with a clock speed of 1605 MHz and a GDDR6 memory frequency of 1750 MHz. It also makes use of a 256-bit bus, and makes use of a 7 nm design. It is comprised of 2560 SPUs, 160 TAUs, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5700 XT		225 Watts
GeForce GTX 980 Ti		250 Watts
	Difference: 25 Watts (11%)

Memory Bandwidth

In theory, the Radeon RX 5700 XT should perform quite a bit faster than the GeForce GTX 980 Ti overall. (explain)

Radeon RX 5700 XT		458752 MB/sec
GeForce GTX 980 Ti		336000 MB/sec
	Difference: 122752 (37%)

Texel Rate

The Radeon RX 5700 XT should be quite a bit (approximately 46%) faster with regards to anisotropic filtering than the GeForce GTX 980 Ti. (explain)

Radeon RX 5700 XT		256800 Mtexels/sec
GeForce GTX 980 Ti		176000 Mtexels/sec
	Difference: 80800 (46%)

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 5700 XT is the winner, but it probably won't make a huge difference. (explain)

Radeon RX 5700 XT		102720 Mpixels/sec
GeForce GTX 980 Ti		96000 Mpixels/sec
	Difference: 6720 (7%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Bandwidth is the max amount of information (measured in megabytes per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
